Abstract
The utility model relates to a metal case capable of preventing entanglement of a terminal connector, which is made of a metal plate body through integral punch molding. The front section of the utility model is bent into a rectangular frame portion and provided with a plurality of narrow slots in a punching way to form a plurality of positioning spring sheets, so that a terminal port body is fastened in the rectangular frame portion. The metal case is downward extended with a plurality of grounding pins, the terminal of each pin is convexly provided with a convex portion, so that each pin can not penetrate the narrow slots of the other metal case during the acid-washing and electroplated manufacturing procedures of the metal case. The entanglement phenomenon can be avoided, and the complete electroplating can be ensured to decrease defective products.
Description
The utility model relates to the line connector in a kind of electricity essential electronic element field, refers to a kind of capable of preventing interwinement metal shell of clamped nipple especially.
The metal shell of the clamped nipple of in electron trade, being habitually practised at present, as shown in Figure 1, this metal shell (100) is by a sheet metal, the integrated punching moulding, make the leading portion of metal shell (100) form a rectangle frame portion (101), and wear a plurality of slits (102), to form a plurality of Location resilient pieces (103), so that fastening double team one terminal body in this metal shell (100), extend a plurality of ground connection legs (104) respectively downwards in the both sides of metal shell (100) in addition, to be fixed on the circuit board; And after the moulding of above-mentioned metal shell (100) usefulness metallic plate punching, must be through the operation of pickling, plating, to make finished product.In above-mentioned manufacturing process, because together mixing, numerous metal shells (100) place descaling bath, electroplating bath to carry out operation, so often cause each leg (104) of each metal shell (100) institute projection to penetrate in the slit (102) of another metal shell (100), easily difficult situation of dividing is entangled with in generation each other, must separate one by one, except that time-consuming, take a lot of work, also in separation process, cause the deformed damaged of leg (104) easily, bring very big trouble for each manufacturing process.
In addition, when each leg (104) of metal shell (100) penetrates in the slit (102) of another metal shell (100), very easily cause pickling, electroplate not exclusively, produce defective products, and increase manufacturing cost.
The purpose of this utility model is to provide a kind of capable of preventing interwinement metal shell of clamped nipple, it is at the prominent respectively teat of establishing of each leg end of this metal shell institute projection, penetrate in the slit of another metal shell with each leg that prevents this metal shell, and cause the situation unclear, that be difficult to separate of being entangled with, in order to manufacturing processes such as pickling, plating, and the defective products when reduce electroplating, improve product quality.
For achieving the above object, the utility model is taked following technical scheme:
A kind of capable of preventing interwinement metal shell of clamped nipple, be provided with metal shell by a metal plate punch forming one, its leading portion bends to a rectangle frame portion, and dash and establish a plurality of slits to form a plurality of Location resilient pieces, in it, and make a plurality of legs of the downward projection of this metal shell with fastening double team one terminal body; Its improvements are that each leg end of described metal shell is prominent respectively establishes a teat, to stop the slit of each leg along another metal shell, stretches in this metal shell.
The utility model embodiment is described with reference to the accompanying drawings as follows:
Fig. 1 is the schematic perspective view of prior art metal shell.
Fig. 2 is the schematic perspective view of the utility model embodiment.
Fig. 3 is the front view of the utility model embodiment.
Fig. 4 is the part amplification view of the utility model embodiment leg.
Fig. 5 is another embodiment schematic perspective view that is used for single-row clamped nipple metal shell.
Fig. 6 be single-row clamped nipple metal shell shown in Figure 5 front view.
See also shown in Fig. 2-4, metal shell of the present utility model (1) is by a sheet metal integrated punching moulding, leading portion at this metal shell (1) bends to a rectangle frame portion (11), and dash and establish a plurality of slits (12), to form a plurality of Location resilient pieces, in it, and make this metal shell (1) projection downwards that a plurality of legs (13) be arranged with fastening double team one terminal body (scheming not shown).Above-mentioned metal shell (1) is to belong to existing structure, is not feature of the present utility model, so seldom give unnecessary details at this.
Each leg (13) terminal (13a) that is characterised in that the projection of above-mentioned metal shell (1) institute of the present utility model, it is the prominent teat (131) of establishing, make each leg (13) at the integral thickness (W) of this teat (131) section greater than original sheet metal thickness (W1), and go up the width of slit (12) greater than metal shell (1), and make metal shell of the present utility model (1) when mixing each other, each leg (13) end of each metal shell (1), because of stopping of teat (131) arranged, can not stretch in the slit (12) of another metal shell (1), thereby can not be entangled with unclear phenomenon, mutual nonaggression, in order to follow-up pickling, electroplate ... Deng manufacturing process, reduce fraction defective, improve the quality of product.
Metal shell of the present utility model (1) can be to apply on the biserial clamped nipple as shown in Figure 2; Perhaps this metal shell (1a) can apply on the single-row clamped nipple shown in Fig. 5,6; The utility model does not limit the form of clamped nipple.
The utility model can be the jut of a spheroidal, oblong or other shape at the dash forward teat (131) established of each leg (13).
From the above mentioned, each leg (13) end that is characterised in that this metal shell institute projection of the present utility model, it is the prominent respectively teat (131) of establishing, to avoid putting a time-out when a plurality of metal shells mix, the leg of each metal shell (13) stretches in the slit (12) of another metal shell, so difficult branch phenomenon can not take place to be entangled with mutually, and it has the following advantages:
1, in manufacturing process, each metal shell is independent clearly demarcated, can avoid existing structure when being entangled with, the trouble that must separate one by one, and can reduce the distortion of each leg of metal shell.
2, can make each metal shell finish manufacturing processes such as pickling, plating fully,, reduce defective products to improve product percent of pass.
Establish a teat (131) though the utility model is only prominent on each leg of metal shell, yet solved the puzzlement of existing metal shell in manufacturing process, and effectively reduce the generation of defective products, have novelty, creativeness, practicality really.
